Common symptoms of central air conditioning (1), drain: refers to refrigerant leakage; electrical (wiring, body) leakage and other damage caused by the insulation. (2), block: refers to fouling and plugging the ice refrigeration system; air filter is clogged; air inlet and outlet are an obstacle blockage. (3) off: an electrical line break; fuse blown; due to overheating or excessive current overload caused by the contact is open; the cooling system pressure caused by abnormal pressure switch contact is opened and the like. (4), burn: refers to the compressor motor windings, fan motor windings, solenoid coils, relay coils and contacts, etc. are burned. (5), the card: a compressor means jammed, jammed fan, moving parts of bearings jam. (6) damage: broken finger compressor valves, piston scuffing, fan blade fracture and various parts breakage. Hanging a fluorine freon air conditioning and how much pressure completely ran away, then, regardless of the model, as long as the pressure of the refrigerant is R22 0.45mpa --- 0.6mpa are Xuzhou air cleaning phone, I mean in the case of cooling Under pressure of the low pressure side, the reason there is such a large span is mainly because of the different departments of the manufacturers conditioned structure, closure systems, as well as the age of your home air conditioning, recommended pressure 0.5mpa, mainly to see the low-pressure pipe temperature, above Xuzhou condensation home air conditioning repair phone, hand feels cool, on the line. There are air conditioning refrigeration are not necessarily no refrigerant, and this is just one of them, you first determine the indoor unit filters and outside the machine Is not unventilated condenser to say, OK, no problem, but the case is still not cooling, to find professionals to see what happens, decrease the amount of air conditioning and refrigeration air conditioning installed idea for several reasons, craft mouth screw not tightened, causing refrigerant leak. As long as this problem tighten the screws, and then make up the refrigerant line. Air conditioning dirty. If the air conditioner is dirty it will result in heat well inside and outside. Like this relatively easy to solve. As long as clean air will solve the problem. Air conditioning refrigerant shortage, will also affect the air conditioning and refrigeration. Since the cooling system leak participate within the system thermal cycling refrigerant (refrigerant) insufficient, resulting in decreased efficiency of heat exchange, resulting in insufficient cooling capacity phenomenon. This Just fill plus snow on it. After long-term use of air conditioning compressor aging, power increases, lower energy efficiency, resulting in performance degradation Xuzhou central air-conditioning transformation, such problems have no good way, only the air-conditioning system for processing, change the air filter, replace compressor oil. (Note: different grades, grade compressor oil Do not mix). If not, you can only replace the compressor or buy a new air-conditioning.
